SPRING FASTENING DEVICE.

necessa- Specification of Letters Batent.

Patented Oct. 10, 19115.

Original application filed. June 22, 1908, Serial No. d39,701.' Divided and this application filed August 20 1909. fierial No. 513,858.

citizen of the United States, and a resident of the borough of Brooklyn, county of Kings, city and State of New York, have invented certain new and useful Improvements in Spring Fastening Devices, of which the following is a specification, accompanied by drawings.

This invention relates to improvements in spring fastening devices for electrical conductors, and the objects of the invention are to enable the conductor to be firmly gripped and maintained in'defined position in the devicet to cheapen the cost of manufacture and enable the devices to be made out of sheet metal and to provide a construclOngitudinaHy into the device and maintained in position.

There are many circumstances in which it is desirable to use a fastening device in which the conductor is inserted longitudinally instead of transversely, and my device accomplishes this object as'well as other objects which will hereinafter appear.

To these ends the invention consists of a fastening device for carrying out all of the arrangement of parts having the general mode of operation substantially as hereinafter fully described and claimed in this specification and shown in the accompanying drawings, in which.

- Figure l is a perspective view of a device embodying-the invention; and Fig. :2 is a similar view of a modification with the wire inserted.

The fastening device is adapted to be secured to a base or support A and in this instance the device is shown secured fiat upon the support, although other means of supporting the device may be provided as desired, according to the nature of the-work for which the device is used.

In Fig. 1, the device':comprises a single piece of metal, although I am not to be understood as limiting the invention in this respect, for each device, may comprise as many separate parts suitably secured together, as may be desired.

In Fig. 1, B represents the body member and G the spring member which is bent over the body member and is normally separated therefrom. The body member is bent longitudinally of its length to form an arch or rib and this rib is slotted transversely at D, leaving two upwardly projecting. resistant portions E. The remainder of the 'body and spring members is preferably slot-ted longitudinally at F and the outer endof the spring member is provided with the wire engagin loop or bend G, which is pressed out of t e metal and is adapted to pass into the slot D between the projecting members it, so'that when a wire H is inserted longitudinally beneath the members E and through the wire engaging portion G, said wire will be gripped at at least three points of contact in the same plane and held in position by the retractive force of the spring.

The device is adapted to be secured to the support A as by means of the screws J.

This invention is a division of'my copending application, Serial No. 439,701, filed June 22, 1908, for spring fastening devices.

.I claim and desire to obtain by Letters Patent the following:

A spring fastening device, comprising a fiat body member of metallic. ribbon, having substantially greater width than thickness and adapted to lie on a base or support and be secured thereto, and an opposing spring member of flat metallic ribbon situated 0pposite and normally separated from said 'body member, one of said members being provided with a transverse slot, and the other with a projecting wire engaging portion adapted to enter said transverse slot in the .opposite member, whereby, when the members are pressed together, a conductor may be inserted longitudinally between said J members, and have exerted upon it at at least three points of contact the pressure due to the resiliency of the spring member.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
